CLOTH-CUTTER.

SPECIFICATION forming part of Letters Patent No. 584,390, dated June 15,1897.

Application filed August 1, 1896. Serial No. 601,842. [No model.)

To ctZZ whom, it may concern:

Be it known that we, PRESTON C. MORSE and CALVIN E. RANDALL, residing atNatick, in the countyof Middlesex and State of Massachusetts, citizensof the United States, have invented a new and useful Improvement inCloth-Cutters, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, forminglo a part of this specification, in explaining its nature.

The invention is an improvement upon that described in the applicationfor Letters Patent of the United States of the said Preston I 5 C.Morse, filed March 4, 1896, Serial No. 581,750; and it relatesespecially to the part therein called the foot of the cutting-ma chine.The said foot is attached to the remainder of the machine by a cross-barand a vertical arm of peculiar structure, from the lower end of whichthe foot extends. The foot is narrow, has astraight under surface orrest, an inclined upper surface, and a section of a shearcutter. It hasbeen found in practice that in turning the cutting-machine upon the bedwhich supports it and the cloth to be cut the foot of the machine whenso constructed cannot always be turned under the cloth without rumplin gthe under layers thereof, and also that on account of inequalities ofthe surface of the said supporting-bed, upon which the foot rests, theforward end of the foot may be lifted slightly fronf the surface of thebed, and when it does not ride upon said surface it is liable to workinto the under layer of the cloth and disarrange it or injure it; andthe present invention consists in a foot somewhat shorter than that ofsaid Morses construction and a supplemental foot or toe which is pivotedor hinged to the main foot to permit its forward end to always conformto the surface of the bed and which is rounded from the upper surface ofthe main foot downwardly and extends laterally, so that it is Wider thanthe main foot, and thus provides for the gradual lifting of the clothwithout disturbing it as it is moved in a curved or lateral directionunder it. There is thus provided a structure which overcomes thedifficulty above mentioned in that the supplemental section shields thefoot proper and prevents rumpling of the lower layers as the foot isturned or advanced and in that the front end of the supplemental footyieldingly conforms or adjusts itself to the surface of the bed uponwhich it is being moved, the said supplemental foot being attached tothe foot proper to permit it to thus adapt itself to the said surface.

We will now describe the invention in connection with the drawings,wherein- Figure 1 is a view in perspective of the lower part of acloth-cutting machine provided with our invention. Fig. 2 is a View inhorizontal section, taken through the lower part of the arm supportingthe foot, and in plan of parts below the same. Fig. 8 is a View in crossvertical section upon the dotted line as or of Fig. 2. Fig. 4 is aviewin longitudinal vertical section upon the dotted line y y of Fig. 2.

e have shown in the drawings only enough of the machine to identify thestructure herein described therewith.

A represents the foot. It extends forward from the lower end of thevertical support a, the vertical support extending from the end of across-bar a, by which it is attached to the frame of the machine. lowerbearing-surface a which is adapted to rest upon the bed or table holdingthe cloth, and over which the cutter is adapted to move. Italso has thesection a of the shear-cutter. The vertical support a has a back face a,which extends upwardly from the end of this cutter. To the forward endof the foot A is attached a supplemental foot 13. This has a fiat undersurface I), a rounded upper surface b, and a recess 12 which receivesthe end of the foot and which ends in the under- The foot has the.

out section 12 the end of the foot preferably extending into theundercut section. The supplemental foot is secured to the foot proper bya horizontal pivot c,passing through both, (see Fig. 3,) and thesupplemental foot may also have extending backward the section b thesaid section preferably being rounded on its upper surface, and beingabove the bottom of the foot If and separated from the side of the footby a space I), which space is in line with the reciprocating cutter D.

ICO

The supplemental foot bears such relation to the main foot that it isfree, when resting upon the surface of a bed or support, to conform tosaid surface at its front edge, and it is so balanced in respect to thepivotal point that the front section is heavier than the rear. Thisalways maintains its under surface at its front in contact with thesurface of the bed upon which it is moved.

The supplemental foot, it will be observed, is cut away in front of themain part of the foot A. This permits the operator to ascertain by hisfingers the position of the foot A when under the assembled layers ofcloth.

It will be seen that the extension 6 acts to support the material backof the foot and back of the line of reciprocation of the plunger-cutter.,It will also be seen that the supplemental foot upon the front side iscut away to expose the front side of the main foot below theshear-cutter.

Having thus fully described our invention, We claim and desire to secureby Letters Patent of the United States 1. The combination of the arm orsupport at having the back face a and the foot A having a shear-cuttingedge a with the plungercutter D and the supplemental foot B pivoted tothe foot A as described, as and for the purposes set forth. 7

2. The combination in a cloth-cutting machine of the foot A having theshear-cutting edge a with the supplemental foot B pivoted to the saidfoot A and having the backward extension 12 separated from the foot by arecess b, as and for the purposes described.

3. The combination in a cloth-cutting machine of the narrow foot A, withthe foot B having the extension 5 shaped to provide a recess b betweenit and the foot, and also having a recess in its under side to receivethe forward end of the said foot Aanda pivot 0 extending laterallythrough the supplemental-foot B and the forward end of the foot A, asand for the purposes set forth.
